With a total of 4 patents to his name, Akamatsu continues to push the boundaries of innovation in his industry.

Latest Patents

Akamatsu's latest patents include an exposure apparatus, an exposure method, and an article manufacturing method. The control unit in his exposure apparatus is designed to manage the relative position in the optical axis direction of the projection system. It also controls the relative position in a direction perpendicular to the optical axis at a third timing after a second timing. This is based on the first distribution of illumination light detected by the detection system at a first timing and the second distribution detected at the second timing. The illumination light detected at these timings has passed through the first and second marks. His exposure apparatus is engineered to perform an exposure process that transfers a pattern from a mask to a substrate. It includes a projection optical system that projects the mask's pattern onto the substrate, a measurement pattern on the object plane of the projection optical system, and a first detection unit that detects light from the measurement pattern.
